Please show us at least the prototype of the C function(s) being called, and
the .C call in the R code.
Just to make sure: The first argument to .C() should be the name of the C
function, not the name of the C source file.

hello, everybody,
I create a package by myself named var on Linux system. I
attach a C code
which uses R_ext/Lapack.h in directory src. But when I
carry out R CMD
check var, it shows
wxt0124()
Error in .C(wxt1221, PACKAGE = var) : C function name not
in DLL for package
var
Execution halted
Could you tell me what is the problem?
